' Thepresentinvention, .as indicated, relates v to adjustablesupports'for drain boards and the/like, and .more'specifically to" meansfor supporting enameled sheet metal drain boards. A The primary objectof the invention is to provide a support of the type in dicaite d whichwill permit' proper location of the drain board with respect to the wallor the backboard of a sink, and which will further be adjustable tomaintain a proper tension upon the drain board itself to preventbuckling. To the accomplishment of the fore:

, going and related ends, said invention, then, consists of the meanshereinafter fully described and particularlypointed out in the claims.

.scription set forth in detail certain mechanism embodying theinvention, such disclosed means constituting, however, but one ofvarious J mechanical forms in which the principle of the invention maybe used.

V Y In s'aidannexed drawing:

Fig. 1 isa' bottom plan view of a drain board equipped with anextensible clamp of (the type contemplated by the present invention;Fig.2 is a transverse section taken substantially on the line 22 of Fig.1; Fig. 3 is a verticalsection taken substantially on the line 33 ofFig. 2; and Fig. 4 is a fragmentary section taken substantially on theline 1 tot Fig. 3.

Referring more particularly to the drawings, the reference numeral 1indicates a drain board formed of enameled sheetmetal. Said drainboardis adapted to be attached to a wall 2 and to abut against the front sur-2 face of a backboard 3 of a sink (not shown). 2 The drain board 1 isprovided with laterally depending flanges 4t and 5 which are inturned attheir bottom edges toform lips 6 and 7 respectively. A bracket 8 issecured to the wall2 by means of screws 9 or similar fastening means,and said bracket carries upwardly projecting bolts lOand 11.

The extensible clamp whereby the drainboard is secured to the bracketcomprises a relatively long strip 12 formed with longitudinallyextending slots 13 and 1 1. One

e end of the strip 12 is bentat right angles to the major portion of thestrip to fornia lug 15 provided with a screw-threaded apertureat rightangles to form a lug 18 similar to the lug 15, said lug 18 beingprovided with a screw-threaded aperture 19. A double ended screw,indicated generally at 2 is provided with right hand threads on its oneend 21, and'with' left hand threads at its other end 22. Intermediatethe two ends 1 j I there is formed a polygonal portion 23 which Theannexed drawin and the followin de-.

is adapted to be engaged by-a wrench. The end 21 of thescrew20 extendsinto the aperture 19 in the lug 18, while the end 22 thereof extendsinto the aperture 16 of the lug 15. v

, "The free end-24 of the strip12 abuts against a block 25 of rubber orsimilar resilient material which is retained against the flange 5 by thelip 7, and the free end 26 of the strip 17 abuts against a similar block27 held against the flange 4:-

The two strips 12 and'17, having been adjustably secured to each otherby means of the screw 20, are inserted between the blocks 25 and 27, andthe screw 20 lei-outed to force the strips 12 and 17 apart, whereby theclamp will exert the desired tensioning force on the drain board; Thestrip 12 is then mounted on the bracket 8 with the bolts 10'and 11 e1:-

t'ending through the slots 13 and 14, respectively, and the drain board1' is brought into the desired relation with respect to the wall 2 orbackboard 3' by shifting said board toward or away from the wall. lVhenthe board has been brought into the desired position, the nuts 28 areturned down on the bolts 10 and 11 to secure the. clamp and boardrigidly in place. The polygonal portion 23 of the screw may be provided,if desired, with sockets 29 for the receptionof a bar to be used inturning said screw. I i 1 Other modes of applying the principle of myinvent-ion may be employed instead of the one explained, change beingmade as regards board tosupport the same;

the mechanism herein disclosed, provided the means stated by any of thefollowingclaims or the equivalent of such statedmeans be employed. V

I therefore particularly point out and distinctly claim asmyinvention 1. The combination with admin board, of

supporting means therefor comprising a relativelylongstriptormed with apluralityof longitudinally extending slots therethrough, j

a bracket, means adapted to coact With said bracket and to pass throughsaid slots to secure said strip to said bracket, and a second relativelyshort strip adjustably secured to slots to secure said strip to saidbracket, an r i angularly pro ecting-lug on one end of said u strip andprovided with i a screw-threaded aperture, a second relatively shortstrip provided atone end with an angularly projecting lug formed with ascrew-threaded aperture, and a right-and-leftdiand screw having one"endjengaged in each ofsaid apertures andad justably securing together.said strips," the transmit operable to move said strips toward or awayfromeach other, and resilient means interposed between the oppositeendsof said strips and said'flanges', respectively, and adaptedto pressurefrom said strips to said flanges. v

6. The combination with drain board, of

supporting means therefor comprising a bracket, an extensible clampsecured tosaid drain board, and means for mounting said clamp on saidbracket, Y

'7. The combination with a drain board having a depending flange on eachof two opposite sides, of supporting means compris ing a bracket, anextensible clamp adaptedto exert pressure against said flanges,resilient means interposed between said clamp and said iian 'es,and'rneans adjustably securing n a 0 said clamp to said bracket. 7
